When you're rebuilding the top end of your engine, getting the right piston rings is critical for proper sealing and performance. This is a steel top ring from CP Pistons, designed for a 4.095 inch bore. It's 1.2mm thick, with a specific RT profile and a .138 inch ring thickness, ensuring it fits precisely into the piston groove.

CP Pistons are known for their well-built components, and this ring is no exception. Using a steel ring like this can offer improved durability and heat resistance compared to some other materials, which is important for keeping your engine running smoothly under load. It’s a key piece for ensuring your pistons create a solid seal against the cylinder walls, preventing blow-by and maintaining compression.
